  • TypeATX
  • Extremely fast wake-from-sleep with Modern Standby compatibility

Compatible Workstation Power Supply

This 1050W ATX unit is built for the XW9400 and XW8600 workstations. It delivers reliable power for professional workloads and multi-GPU configurations. The server-grade design suits demanding creative and compute tasks. It replaces part numbers 440860-001 and 442038-001 directly.

80 PLUS Gold Efficiency and Headroom

The Gold rating ensures high efficiency across typical loads, reducing waste heat and fan noise. At 1050W it handles heavy CPU and GPU draw with comfortable overhead. Peak demands beyond the rated wattage will trigger protection shutdown. Sustained loads near the limit increase fan speed and temperature.

Modern Standby and ATX Limits

Modern Standby compatibility enables rapid wake times and deeper sleep states supported by the platform. The ATX form factor and connector layout restrict use to compatible workstation chassis. Proprietary pin-outs on the XW9400 and XW8600 prevent installation in standard desktop cases. Zero RPM mode functions only within the unit's low-load thermal envelope.

Questions about this item

Will this 1050W supply fit and power my existing HP XW9400 or XW8600 workstation?

The unit is built for the HP XW9400 and XW8600 chassis and delivers 1050W through the standard ATX connector layout used by those models.

How can I confirm the 80 PLUS Gold efficiency and Zero RPM fan mode are active after installation?

At idle the fan should stay completely off, and under load the PSU will meet 80 PLUS Gold efficiency levels, running cooler and quieter than lower-rated units.

Does the package include the original HP part numbers 440860-001 and 442038-001 or do I need extra cables?

The power supply ships as a direct replacement matching both HP part numbers; no additional cables or adapters are required for the XW9400 or XW8600.
